High-Speed Metal Objects Detection Using Interreflection Region Estimation Method
Shinichi Sumiyoshi, Yuji Sakamoto (Hokkaido University) MVE2020-1
Abstract (in Japanese) (See Japanese page) 
(in English) It is necessary to discriminate metal objects at high speed with a low-cost sensor for automatic sorting
of waste.
In this research, we propose a method for estimating the area where metal objects are present from the
target scene using a projector camera system.
The proposed method uses a method that can separate and acquire interreflected lights and directly reflected lights generated from metal objects, and detects the region which the interreflection occurs as the existing region of the metal objects.
Experiments were conducted in simple scenes with a lambert reflector object and a metal object, and it was confirmed that the metal objects could be detected.
